Product Summary

Precision spindle bearings are single row angular contact ball bearingscomprising solid inner and outer rings and ball and cage assemblies with solid window cages. They cannot be dismantled. The bearings are available in both open and sealed versions. Yet, they have restricted tolerances. They are particularly suitable for where requires very high guidance accuracy and speed capacity, especially for slewing part of the main spindle of machine tool.

Meanwhile, Precision spindle bearings own the characteristics of super high-speed, high-precision, high efficiency, micro-precision bearings manufacturing process with the inner circle is efficient grinding tool, but also other sectors within the round holes of the grinding machine parts bound election.

Furthermore, with performance analysis, reasonable structure, excellent technical performance, Precision spindle bearings are particularly suitable for supporting high axial forces. They are directly interchangeable with spindle bearings of series B719 and B70 and offer even more precise machining results and higher cutting performance for the application. So they should be used wherever operating conditions call for superior accuracy, very high speed, quiet operation (low noise and vibration).
